Frequently asked questions
Are my files uploaded?
No. Model parsing, preview, and export run in your browser.
Is the conversion lossless?
No format conversion is described as lossless. Review the format-specific warnings above before using the output.
What is the file-size limit?
100 MB is a safety ceiling, not a guarantee. Mobile devices may need substantially smaller files.
